I unfortunately HAD to get a stupid thermostat with wifi. can't even get one without it now. I'd much rather have it not hooked up but I may be forced to.

How can I put this on a VLAN and block all it's telemetry? It's a honeywell. Can i put it on my VLAN and then use mullvad DNS to block all the shit?

"They" are saying it has to be on wifi so it can see the outdoor temp to talk to the heat pump. Bullshit i say.

My Honeywell T10 is connected to my wifi, I use the Homekit on it with HA. But I setup a firewall rule in my router to block all outgoing internet traffic to a group if IPs. Then I added my smart vacuum, thermostat, printers, doorbell, etc to the group. It's a solid setup.

This was going to be my suggestion -

Isolate it in a VLAN, don’t create NAT rules for that VLAN. Just let it exist. Only allow inbound traffic from other VLANs if needed.
